As i start up my max, about the first mile or two i drive whenever I hit a bump there is knocking in the rear as if something were loose. I checked and nothing is loose and it only knocks about the first mile or two. My max has 75k miles on it. HELP PLEASE?

 

That is something you are going to have to find yourself but it could be the exhaust or if it is more of a clunking then it could be the struts as well
